Figure. Phylogenetic analysis of hepatitis E virus (HEV) isolates from specific pathogen-free (SPF) rabbits, China, 2012−2015. The phylogenetic tree was constructed by using the neighbor-joining method, a partial nucleotide sequence of the open reading frame 2 region, and reported HEV sequences in GenBank as references. One thousand resamplings of the data were used to calculate percentages (values along branches) of tree branches obtained. Black circles indicate SPF rabbit isolates obtained during this study. GenBank accession numbers of all reference sequences (in parentheses) are FJ906895 (GDC9), AB740222 (rbIM004), JX565469 (CMC-1), AB740221 (rbIM022), GU937805 (ch-bj-n1), JX121233 (CHN-BJ-R14), JQ013793 (TLS-18516), JQ013792 (W7-57), AF455784 (Osh-205), AF060668 (US1), AY115488 (swArkell), AB189070 (JBOAR-1Hyo04), AP003430 (JRA1), JF309217 (GS-NJ-10), AY723745 (IND-SW-00-01), AB097812 (HE-JA1), M74506 (Mexican), AY204877 (T3-Chad), and AF459438 (Yam67). Scale bar indicates nucleotide substitutions per site.
